A new study has revealed that individuals who suffered severe COVID-19 infections during the pandemic’s first wave are facing double the risk of heart attacks and strokes. According to the study, the risk of heart attack, stroke, and death remains significantly elevated for more than three years after initial infection. This increased risk is particularly pronounced among those who required hospitalization during their illness, whose chances of cardiovascular events were four times higher than those who never had COVID-19.
Lead researcher Dr. Hooman Allayee of the Keck School of Medicine at the University of Southern California emphasized the gravity of the findings: “Severe COVID-19 infection is proving to be a catastrophic component to long-term heart health. We have seen ten years of cardiovascular mortality progress wiped out between 2020 and 2022 because of COVID-19.”
The study also drew attention to blood type as a contributing factor, with individuals having blood types A, B, or AB experiencing higher cardiovascular risk compared to those with type O blood, which seemed to offer some protective effect.
The study’s analysis, supported by the National Institutes of Health, was based on data from the UK Biobank, which predominantly includes older, wealthier, and white individuals. However, similar studies involving different populations have shown parallel outcomes, underscoring the universality of these long-term cardiovascular risks.
The research underscores the critical importance of COVID-19 vaccinations in reducing heart-related complications. “Regardless of which vaccine you received, the chances of heart attack and stroke were lower within six months of vaccination,” Allayee explained. However, he warned that immunity from vaccines wanes over time, stressing the need for regular booster shots to maintain protection.
For individuals who have experienced severe COVID-19, particularly those requiring hospitalization, Dr. Allayee strongly recommends discussing potential long-term health risks with their healthcare providers. “It’s time we start acknowledging that COVID-19 isn’t going away, and its effects on heart health are long-lasting. Stay current with your vaccines, boosters, and routine medical check-ups,” he advised.
As the world continues to grapple with the aftermath of the pandemic, this study sheds light on the hidden dangers COVID-19 poses, even years after recovery. The findings serve as a reminder that vigilance in personal health and preventive measures like vaccinations are vital in mitigating future risks.
